The pressure exerted by a gas in a container depends on what?

lyudmila [28]

Answer:

From gas laws (pressure law and Boyles law), the pressure exerted by a gas depends on Temperature of the gas and volume of the container.

Explanation:

${ \boxed{ \rm{P \: \alpha \: \frac{T}{V} }}}$

• P → Pressure exerted by the gas.

• T → Temperature of the gas.

• V → Volume of the container.

• from the expression, pressure exerted by the gas is directly proportional to temperature of the gas and inversely proportional to the volume of the container.
